Serotonin is a neurotransmitter, a chemical messenger in the brain that helps regulate mood, appetite, and sleep, among other functions. It is sometimes referred to as the “feel-good” hormone because it plays a key role in promoting feelings of happiness and well-being.
Serotonin is produced in nerve cells and released into the brain and bloodstream, where it binds to receptors and influences varios physiological processes.
Imbalances in serotonin levels have been linked to conditions such as depression, anxiety, and eating disorders, and medications that target serotonin are often used to treat these conditions.
